The calcium oxide combines with silicon because the oxygen scavenger, yielding the incredibly stable calcium silicate and releasing unstable (at significant temperatures) magnesium metallic.

It is necessary to Be aware, on the other hand, that even though the inclusion of calcium silicate in foods is controlled, the diversification of its takes advantage of throughout industries usually contributes to different degrees of purity and excellent.

In conclusion, calcium silicate (E 552) is really a usually utilised anti-caking agent inside the meals field, contributing to the texture, flowability, and shelf security of processed foods and beverages. Although it is usually considered Safe and sound for usage, safety measures must be taken to minimize inhalation of silica dust and stay away from too much intake to mitigate potential health and fitness read more dangers.

Consequently It's not anticipated to react chemically with other elements of our food stuff during digestion.
